Academic Honesty is about producing original work that includes thought, creation and synthesis of knowledge and gives proper credit to the sources you use.
Plagiarizing, whether intentional or by accident, is a violation of the Academic Honesty Policy.
"All work submitted for academic evaluation must be the student's own. Certainly, the activities of other scholars will influence all students. However, the direct and unattributed use of another's efforts is prohibited, as is the use of any work untruthfully submitted as one's own."
